It feels like a hybrid of a classic Chris Roach and a modern Devid Vii creation in terms of engineering and proportions. As an homage to the classic G1 toy it is spot on and I really like it. Trouble for me is that I'm used to LegoPrime's taking inspiration from the Masterpiece figure, so tricks like hand transformations and chunkier proportions, so part of me thinks "it's great, but the next version will be perfect".
